It is said that as many days as there are in the whole journey, so many are the men and horses that stand along the road, each horse and man at the interval of a day’s journey; and these are stayed neither by snow nor rain nor heat nor darkness from accomplishing their appointed course with all speed.

We are mothers and fathers. And sons and daughters. Who every day go about our lives with duty, honor and pride. And neither snow, nor rain, nor heat, nor gloom of night, nor the winds of change, nor a nation challenged, will stay us from the swift completion of our appointed rounds. Ever.[5]

A corrupted version of this creed appears in Thomas Pynchon's The Crying of Lot 49 as the creed of the fictional Tristero postal service. The creed as Pynchon has it goes thus: '[...] neither tempest nor strife, nor fierce beasts, nor the loneliness of the desert, nor yet the illegitimate usurpers of our rightful estate, can deter our couriers.'
